adj.與其他天體作同方向運(yùn)行的

Prograde orbits are more vulnerable than retrograde ones. 因此順行的軌道會(huì)比逆行軌道更加脆弱。

A surprise in this computation is the presence of prograde motion in the fundamental mode. 一個(gè)意外的計(jì)算結(jié)果是在基本型中出現(xiàn)前進(jìn)運(yùn)動(dòng)。

Type V (occlusion group). Lesions have no prograde flow and no lumen is identified. 型（閉塞組）：沒(méi)有前向血流，沒(méi)有管腔。

If irregular moons were originally equally likely to be either prograde or retrograde, this resonance could explain why most moons are now retrograde. 若順行與逆行的不規(guī)則衛(wèi)星數(shù)量原本是平均分布的話，那麼此共振態(tài)便可以解釋為什麼現(xiàn)在大部份的不規(guī)則衛(wèi)星都是逆行的。

Braided-river deltas that braided river systems prograde into an inland lake are first found in the Palaeogene Shahejie Formation in the Gudong area, Shengli Oil Field. 勝利油田孤東礦區(qū)老第三系沙河街組中發(fā)現(xiàn)豐富的湖泊辮狀河三角洲沉積物,其特征顯著,明顯有別于其他類型的三角洲,可見(jiàn)到8種特征各異的微相。
